The CPT values in the affected leg in patient group were significant higher than those in control group at all frequencies. The CPT values in contralateral leg in patient group were significant higher than those in control group at 5Hz whereas there were no significant differences at 250Hz and 2000Hz. The CPT values in affected leg in patient group were significant higher than those in contralateral leg at 250Hz and 2000Hz whereas there were no significant differences at 5Hz. All the CPT values showed the same linear decrease from the dermatome of the compressed root to the dermatomes of the contralateral neighbor dematom.
在用CPT监测8例腰骶单神经根病组患侧和健侧及与正常对照组的不同直径感觉神经纤维功能的研究中发现压迫皮节和其临近皮节的所有频率CPT值无任何显著性差别;患者压迫侧的2000Hz及250HzCPT值及压迫侧和对侧的5HzCPT值与正常对照组都有显著性差别;患者组5HzCPT值患侧和对侧无差别,其他两组均有显著性差别;不管有无显著性差别,神经根病患者组各皮节三频率CPT值均按照压迫皮节,临近皮节,压迫对侧皮节,压迫对侧临近皮节的顺序减小,说明在腰骶单神经根病中Aβ纤维及Aδ纤维及无髓C纤维均受累。

In response to repetitive strain and inflammation, the synovial l-z joints can fill with fluid and distend, resulting in pain from stretching the joint capsule.71 Distension of the articular recesses can also compress the exiting nerve root in the neural foramen or spinal canal, especially when the foramen is already narrowed by joint hypertrophy and/or osteophytes.
反复的应力与炎症反应,可使滑膜l-z关节充满滑液并扩张,导致关节囊收到牵拉产生疼痛。关节囊隐窝的扩张可以压迫神经孔出的神经根出口或压迫椎管内脊髓,尤其当由于关节肥大和/或骨赘形成已经存在椎间孔狭窄时发生率更高。

Essential hypertension caused by neurovascular compression of the left ventrolateral medulla was associated with malbalance of vasomotor center in the dorsal medulla. The possible pathogenesis was the following:① An irritation of the left RVLM by pulsatile compression of an ectatic vessel would increase activity of central sympathetic neuron.② Neurovascular compression at the REZ of the cranial nerves Ⅸ and Ⅹ decreased excitation of parasympathetic nerve.③ Decreased sensitivity of afferent inputs to neuron of nucleus tractus solitarii in the sensory area lead to hyperactivity of central sympathetic nervous system due to pulsatile compression of the left RVLM.④ Neurocompression of the left RVLM and REZ in the left cranial nerves Ⅸ and Ⅹ lead to an overactivity of central renin angiotensin system.
3,结论:左侧延髓腹外侧Ⅸ、Ⅹ颅神经REZ动脉血管压迫所导致的高血压的发生与左侧延髓血管运动中枢对血压的调节失衡有关,其可能机制是:①左侧RVLM在搏动性血管压迫刺激下,中枢交感神经元活性增高;②左侧Ⅸ、Ⅹ颅神经REZ受压导致副交感神经兴奋性降低;③感受区孤束核神经元接受迷走神经传入冲动的敏感性减低,导致中枢交感神经活性增高;④左侧RVLM及Ⅸ、Ⅹ颅神经REZ受压引起中枢RAS活性增加。

RESULTS:①The myelography and CTM revealed that factors contributing to DLSS included not only zygapophysial joint hyperplasy, hypertrophic ligamentum flavum and intervertebral disc protrution which resulted in degenerative lumbar spinal stenosis, but also zygapophysial joint semiluxation and pedicle shift.
结果:①脊髓造影与CT脊髓造影的表现:DLSS对硬膜囊或神经根的压迫较退行性腰椎管狭窄症复杂,除与关节突肥大增生、黄韧带肥厚、椎间盘退变突出有关外,还与关节突关节半脱位、椎弓根移位压迫神经根等因素有关。

The significance was showed by the chisquare test (P.005);(2) The conventional MRI demonstrated that positive sign was 50.9% on the symptomatic side and 6.1% on the unsymptomatic side.
有三叉神经痛症状的一侧血管接触、压迫神经的比率明显高于非疼痛侧,其阳性率差异有显著意义(P.005);(2)MRI常规扫描发现有三叉神经痛症状的一侧血管压迫神经阳性率50.9%,非疼痛侧阳性率6.1%。

Results: Dynamic observation with histopathology and immunohistochemical staining showed that, after the nerve root nerve root compression, the myelinated nerve fibers decreased and there was ultrastructure changes of the nerve fibers, such as Schwann cell cytoplasm swelling and edema, Wallerian degeneration, and demyelinated degeneration of axons.
结果:通过对压迫神经根及神经根节大体观,组织病理学和免疫组织化学的光学显微镜的动态观察,可见神经根压迫后其有随神经纤维数目减少和超微结构的改变,如神经模细胞胞质肿胀和细胞水肿、华勒变性、神经轴突脱髓鞘变等。

地震致闭合性周围神经损伤多为挤压或压迫时间过长所致,早期及时进行正规的综合治疗,预后一般较好;对部分压迫伤较重、压迫时间较长、神经损伤较重者,应积极进行手术松解。

Methods Twenty eight pure New Zealand rabbits were used, of which four were for nerve localization and the rest were randomized into untreatment group and ultrashort wave groups, after the establishment of the nerve root compression models by inserting a silastic tube into the intervertebral canal to compress the sixth and seventh left lumbar nerve roots.
方法纯种新西兰成年兔28只,4只作神经定位解剖,其余24只全部做手术造成腰神经慢性压迫,随机分成2组,未处理组和超短波组,每组又分10 d组、30 d组和180 d组。压迫模型:将硅胶管从椎间外孔缓慢塞入椎间管内,压迫腰6和腰7左侧神经根直到实验兔被处死,右侧为自身对照侧。
